<h1>Immigration enforcement subpoenas target state and local officials over alleged obstruction of federal operations, with injunctions and constitutional claims pending.</h1> Federal prosecutors served grand jury subpoenas on state and local officials to obtain records investigating whether their public statements or actions obstructed federal immigration enforcement, with the probe grounded in potential conspiracy and obstruction statutes; subpoenas compel production of communications and cooperation records and may lead to grand jury proceedings. Separately, state and municipal plaintiffs seek injunctions to limit a federal enforcement surge, alleging constitutional violations including free speech and unlawful use of force; the federal government contends enforcement is within federal authority and reports high arrest numbers, with litigation over scope and remedies pending in federal court.
